Because that student cooperated, he is not facing charges, but a grand jury has indicted a second student -- one prosecutors said was behind the plan and who they believe was a major supplier to a local college community.

Among the drugs found were 138 Xanax pills and 24 ounces of liquid codeine.

"I'd say this is actually a pretty typical case in terms of drugs," said Assistant Commonwealth's Attorney Emily Wilkey.

Wilkey said how those drugs made it back to the Louisville area is anything but typical. She said two students at Kentucky State University devised a plan -- when D'ante Granger went home to Detroit for his grandmother's funeral, Evan Johnson asked him to meet up with "his girl" to pick up the drugs and bring them back to Franklin County.

"You'd like to think a kid with a head on their shoulders heading to college would have a little more sense and obviously have a little bit of respect for his family and grandmother," said Wilkey.

Granger was on his way home when vehicle enforcement made a routine check of the bus. In his duffel bag, Wilkey said they found the Xanax hidden in other pill bottles.

"And then the codeine was repackaged into two 12-ounce water bottles," said Wilkey.

Granger agreed to cooperate, carrying through with plans of a money and drug trade-off on campus.

"His help was pretty pivotal," said Wilkey.

Wilkey said getting Johnson off the streets was crucial.

"I wouldn't think this is Mr. Johnson's first rodeo. My guess is he had been trafficking for awhile and finally they were just able to catch him," said Wilkey.

Wilkey said it's a bust she hopes has other dealers and users re-evaluating their actions.

"Hopefully, it makes other students on campus think twice," said Wilkey.

It wasn't pure luck that led vehicle enforcement officers to the bus Granger was riding back in September.

Buses coming in state are frequently searched. Since Kentucky's House passed a bill last year making it more difficult to traffic prescription pills, more and more dealers are turning to other states with more lax laws to get their supply.

An arrest warrant was issued for Johnson Thursday night. He's been charged with drug trafficking and will be arraigned one week after he's in police custody.
